(a) Given a vector field F(x, y, z) = ( x2 2 + 23 ) i+4 cos (12 z2 ) j + sinh (2 y + 2z) k, If the curl of F is given by V X F = f (x, y, z) i + 8 (x, y, z) j + h(x, y, z) k then, in Maple syntax, f ( x, y, z) = (b) If p(x, y, z) is a scalar field, enter V x ( V d) as a column vector in the box below
